♦ Read through this guide before attempting to use

your new dishwasher.

♦ Read the “Washing Special Items” section before

washing any porcelain or china that has “on-glaze”

decoration, crystal glassware, or items of wood or

plastic.

♦ Make sure the door is properly balanced. To do this,

open it a little and release it. It should stay where you

released it. If it doesn’t, consult the Installation

Instructions or contact your installer.

♦ Call your local water company to learn the water

hardness in your area. You’ll need to know this to

determine how much detergent and rinse aid to use.

This manual does not cover all possible conditions and

situations that may occur. Common sense and caution

should always be used when installing, operating, and

maintaining any appliance.

♦ Read all instructions before using the dishwasher.

♦ Dishwashers must be electrically grounded. Read

the Installation Instructions for details.

♦ Use the dishwasher only for its intended purpose.

♦ Do not run the dishwasher while you are out of the

home.

♦ Use only automatic dishwasher detergents and

rinse agents.

♦ To reduce the risk of injury, keep detergents and

rinse aids out of the reach of children.

♦ Do not load sharp items near the door; you could

damage the door seal.

♦ Place sharp knives in the silverware basket with the

sharp ends down to avoid the risk of cut-type injuries.

♦ Do not wash plastic items unless they are marked

“dishwasher safe” or the equivalent. For items not

marked, check the manufacturer’s recommendations.

Items not dishwasher safe could become deformed

or melt and create a potential fire hazard.

♦ Do not touch the heating element during or imediately

after use.

♦ Do not operate the dishwasher unless all enclosure

panels are properly in place (i.e., guard plate, access

panel, toe kick, etc.)

♦ Do not tamper with controls by removing or changing.

♦ Do not abuse, sit on, or stand on the dishwasher

door or baskets .

♦ To reduce the risk of injury, do not allow children to

play in or on a dishwasher.

♦ Under certain conditions, hydrogen gas may be

produced in a hot water system that has not been

used for two weeks or more. HYDROGEN GAS IS

EXPLOSIVE. If the hot water system has not been

used for two weeks, before using the dishwasher

turn on all hot water faucets and let the water flow

from each for several minutes. This will release any

accumulated hydrogen gas. As the gas is

flammable, do not smoke or use an open flame

during this time.

♦ When removing an old dishwasher from service or

discarding it, remove the door to the washing

compartment.

♦ Do not store or use combustible materials, gasoline,

or other flammable vapors and liquids in the vicinity

of this or any other appliance.

♦ Disconnect electrical power to dishwasher before

servicing.

♦ Repairs should be done by a qualified technician.

The silverware basket is designed with eight compartments to

help keep the silverware separated. Load silverware with the

handles downwards and spread it out as much as possible to

avoid nesting. For safety, load sharp knives with the handles

up.

Avoid placing silverware made of different materials (e.g., silver

and stainless) in the same compartment because of the risk

of discoloration. (See page 14.)

Small Items Containment Lid

The silverware basket has a lid in the middle that snaps down

over the compartments to its left or right to contain small,

lightweight items that might slip through the rack tines or get

washed out of the basket. The small items lid is slotted, so

you also could use it to keep silverware separated, such as

teaspoons.

When loading silverware, try to

avoid nesting the spoons and forks.

LOADING THE UPPER BASKET

After you have scraped off the large food particles, place

glasses, cups, saucers, bowls and small plates in the upper

basket, as illustrated.

Load stemware with the stem fitted inside one of the grooved

tines on the stemware rack.

The fold-down cup shelf on the right side of the basket gives

you an additional place to stack cups and small bowls. You

can also stack items on the stemware rack.

This model has a knife stop on the front of the upper basket.

This gives you a safe place to load long utensils and knives

that won’t fit in the silverware basket. The knife stop prevents

knives or utensils from damaging the door when you open

and close it.

NOTE: When loading sharp items, always be careful not to

cut the rack coating.

Your new dishwasher features ASKO’s Super Cleaning

System™. This means that after prewash, mainwash

and intermediate rinse the water is drained out and the

cycle continues with clean water.

If you plan to start your dishwasher right away, it’s not

necessary to rinse the dishes. You do, however, need

to scrape off the large particles of food before loading.

Load larger items in the lower basket, such as, dinner plates,

pots and pans, serving dishes, and casseroles. Be sure to

load dishware facing downward or toward the center of the

dishwasher.

ASKO dishwashers are designed to be energy efficient.

Because the machine uses less water than conventional

dishwashers, you also use less detergent and rinse

aid. Generally, only one tablespoon of detergent is

needed for a normal wash load. The amount of detergent

needed for your dishes, however, could be more,

depending on the hardness of the water in your area.

(See below.) Also, more heavily soiled items need more

detergent.

Measure and place detergent for the main wash into the

large detergent compartment. The detergent for prewash

goes into the small compartment to the right of the main

wash compartment. You should use one-half the

amount of detergent for the prewash that you use for the

main wash. The amount of detergent used for the main

wash and prewash combined should never be over

three tablespoons.

Always add the detergent just before starting the

dishwasher, otherwise it could get damp and won’t

dissolve properly.

We recommend that you use only unscented, granular

automatic dishwashing detergent. Using the wrong

detergent could cause flooding and/or damage your

dishwasher. Do not use detergent that has been wet

and is clumped. Also, check the expiration date on the

container.

The amount of detergent needed can vary due to

differences in water hardness. To determine the water

hardness in your area, contact your local water utility or

area water softening company. The harder the water,

the more detergent you may need. Refer to the chart

below for the recommended detergent amounts based

on water hardness. Remember, you should adjust the

amount of detergent you use by small amounts until

you find the correct amount.

NOTE: Model D3251FIWS has a water softener

container. See page 6 for more details.

NOTE: We recommend that you do not add

prewash detergent for the Delicate or Quick

wash programs.

NOTE: If you use a dishwashing detergent with a

rinse aid additive, you should not fill the

rinse aid dispenser. This could cause a film

on your dishes.

NOTE: We recommend that you do not add

prewash detergent for the Delicate or Quick

wash programs.

Twelve grains and higher is extremely hard water and

detergent alone may not be enough. You may need to

use a water softener to maximize the performance of

your dishwasher. (Model D3251FIWS is equipped with

an internal water softener. See page 6 for details.)

In areas with extremely hard water (9+) you may need to

wash at lower temperatures to prevent hard water

deposits from forming in the tank and wash system.

Also, both the dishes and the machine can develop a

white or gray film after a while. This can be removed by

replacing the prewash detergent with two tablespoons

of citric acid. If the water is very hard, use a rinse aid that

contains citric acid.

Different brands of dishwasher detergent have different

amounts of phosphorous for softening water. If you have

hard water and use a detergent with less than 8.7%

phosphorous content, you may need to use more

detergent or use a detergent with more than 8.7%

phosphorous content.

If you decide you need a water softener, fill the softener

container with salt as follows:

1. Unscrew and remove the container cover.

2. Place the funnel supplied with the dishwasher into

the fill hole.

3. Pour in approximately 4 cups (1 litre) of water.

4. Pour in about 3 pounds (1.5 kg) of coarse salt or

special dishwasher salt.

5. Wipe away excess salt so the cover can be properly

screwed into place.

6. Run a Normal wash program so that any salt in the

machine is rinsed out.

WARNING!

Never pour dishwasher detergent into the softener

container. It will ruin the water softener.

The dishwasher is delivered with the low water

hardness setting, so you may need to reset it. To do

this, follow the steps below:

1. Turn off the power to the dishwasher.

2. Hold down the Start/Stop button while you press the

Power button to turn the machine back on.

3. Release the Start/Stop button.

This model has an indicator on the control panel that

displays when the rinse aid dispenser is nearly empty

(see page 8). After you refill the dispenser, there may be

some delay before this indicator light goes out.

A measured amount of rinse aid is released during the

final rinse. As with detergent, the amount of rinse aid

needed for your dishes depends on the hardness of the

water in your area. (See page 5.) Too much rinse aid

can result in lather or foaming and cause cloudiness or

streaks on your dishes. If the water in your area is very

soft, you may not need rinse aid. If you do, you can dilute

the rinse aid with an equal amount of water.

The rinse aid dispenser has six settings. Always start

with the dispenser set on “1.” If spots and poor drying

are problems, increase the amount of rinse aid

dispensed by removing the dispenser lid and rotating

the dial to ”2.” If the dishes still aren’t drying properly or

are spotted, adjust the dial to the next higher number

until your dishes are spot-free.

To increase the amount of rinse aid released

in the final rinse, turn the adjustment dial to

the next higher number.

As the rinse aid diminishes, the size of the

black dot on the rinse aid level indicator

changes, as illustrated below.

The rinse aid is released during the final rinse to prevent

water from forming droplets on your dishes that can

leave spots and streaks. It also improves drying by

allowing water to “sheet” off the dishes.

ASKO dishwashers are designed to use liquid rinse

aids. The rinse aid dispenser is located inside the door

next to the detergent dispenser. (See illustration on page

3.) To fill the dispenser, open the cap and pour the rinse

aid into the dispenser until the level indicator turns

completely black. The dispenser holds about four

ounces of liquid rinse aid.

Be careful not to overfill the dispenser, because this

could cause oversudsing. Wipe away any spills with a

damp cloth. Don’t forget to replace the cap before you

close the dishwasher door.

If you have soft water, rinse aid may cause a white film to

develop on your dishes. You may not need rinse aid.

NOTE: If you use a dishwashing detergent with a

rinse aid additive, you should not fill the

rinse aid dispenser. This could cause a film

on your dishes.

programs are described below:

Pots and Pans (170°/Sani or 140° F)

For the heaviest soiled loads, such as casseroles, sauce pans, etc.

Heavy Wash (160° F or 130° F)

For heavily soiled loads, such as pots, pans, casseroles, etc.

Normal Wash (130° F or 140° F)

For normally soiled loads, such as plates, glasses, bowls, and lightly soiled pans.

Delicate Wash (105° F or 120° F)

For delicate items, such as fine china and crystal, that are washed immediately after use. When

using this program, you should set the temperature to low and dry the dishes without heat.

Quick Wash (85° F or 120° F)

For lightly soiled loads that are washed immediately after use. This program can also be used for

delicate items, but you should set the temperature to low and dry the dishes without heat.

Rinse and Hold

To rinse dishes that you plan to wash later that day.

Upper or Lower Basket Only

This option lets you wash only the upper or lower basket. This means mainly the upper or lower spray arm will

function. The upper basket indicator light on the option button will glow when only the upper spray arm is

activated. The lower basket indicator light will glow when mainly the lower spray arm is activated. Both lights will

glow when both spray arms are activated.

Temperature

The dishwasher has two temperature options for each wash program, as shown above. When this button is

set on the high temperature, the main wash is heated to the higher temperature for the selected program. If

it is set to low, the main wash is heated to the lower temperature. The indicator light will glow only when the

higher temperature is selected.

Delayed Start

This button allows you to delay starting the dishwasher for five hours. Press this button then press Start. The

button will glow when Delay Start is selected. To cancel Delay Start, hold down the Start/Stop button for three

seconds.

Drying

This option speeds up the drying process by raising the temperature in the final rinse to 160° F to heat the

dishes and tank before the drying cycle begins. The indicator light will glow only when this option is activated.

Express

This option reduces the wash time and lowers the wash temperature by 18° or 20° F. Express is not available

with the Quick Wash and Rinse and Hold Programs.

PROGRAM TIMES

The program times may not always be the same

because of variations in the household hot water

temperature. The dishwasher heats the water to the

proper temperature for the program selected; so if the

temperature of the water entering the dishwasher is

too low, the dishwasher will run longer because it takes

longer to heat the water. Raising your water heater

setting could help to shorten the cycle times.

On occasion something may get through the filters and

into the drain pump. The drain pumps on ASKO

dishwashers are designed to automatically reverse if

anything should get caught in the propellers, thus

ejecting the item back into the sump area or down the

drain. Should you need to remove an obstacle from the

drain, first turn the power off then remove the filters (as

explained on page 9). Next, lift out the adaptor piece on

the left side of the sump area. (You might want to remove

any standing water first.) You can then look into the sump

area for the item causing the obstruction. You may need

to use your finger to move the pump blade and loosen

the object. Should you find something, simply scoop it

out then replace the adaptor piece and the filters.

The interior of your ASKO dishwasher is made of

surgical quality stainless steel that has been electro-

polished to make it the smoothest surface available.

The smooth surface prohibits the accumulation of dirt

and bacteria inside the unit. If the water in your area is

especially hard, however, lime deposits could form

Main filter

Food and soil particles trapped by this filter are

pulverized by a special jet on the lower spray arm

and washed down the drain.

Fine filter

This filter holds soil and food residue in the sump

area and prevents it from being redeposited on the

dishes during a cycle.

For your convenience, we have placed the drain pump

and filtering system within easy reach inside the tub.

There are three components of the filtering system: the

main filter, the coarse filter, and the fine filter.

In hard water areas, it may be necessary to clean

chemical buildup from the filters every 12 to 18 months.

them by putting two tablespoons of citric acid in the

detergent compartment and running a Normal

program. In extremely hard water areas you may need

to repeat this process a few times to remove hard water

To do this, remove the coarse filter by squeezing the

tabs and lifting it out. Next, unscrew the fine filter and lift

it and the main filter out. Wash all three filters gently in

hot, soapy water and rinse them thoroughly.

WARNING!

Never run the dishwasher without the filters in place.

To clean the edge around the door, use only a soft warm,

damp rag. To prevent penetration of water into the door

As with any new appliance, it sometimes takes using it a

few times to learn to operate it properly. If you are having

minor performance problems with your dishwasher, read

this section before calling for service. It may save you

time and unnecessary expense.

NOTE: ASKO has no control over what is put in our

appliances once installed in a customer’s home. You

are solely responsible for what you wash in your ASKO

dishwasher.

Poor washing performance

♦ The dishes may not be loaded properly. Make sure

that soiled surfaces are facing downward or toward

the center of the dishwasher. Also, make sure that

the bowls, pots, etc., are not stacked so closely that

water can’t reach the soiled surfaces.

♦ Make sure you are using the appropriate program

settings for the dirtiness of your dishes.

♦ An item may be obstructing the spray arm rotation.

With the baskets loaded and in place, manually turn

the spray arms to make sure they move freely.

♦ Your dishwasher detergent should be fresh and

stored tightly closed in a cool, dry place. Old or caked

detergent will not dissolve properly. Wait until you

are ready to start the dishwasher to add the

detergent. If you are using the Delay program, make

sure the dispenser is dry before adding the

detergent.

♦ Your dishwasher detergent may be inferior. Try a

different brand.

♦ Make sure the rinse aid dispenser is filled. (See

page 7.)

♦ If you have hard water in your area, try adding more

detergent and increasing the amount of rinse aid

dispensed. (See page 7.)

♦ Check that the spray arm jets are not clogged.

♦ Do not overload the dishes and be careful to avoid

nesting.

Poor drying performance

♦ Select the Heated Dry option.

♦ If you don’t want to use Heat Dry, you can decrease

the drying time by opening the door slightly to let out

the warm, humid air.

♦ Make sure the rinse aid dispenser is filled. (See

page 7.)

♦ Make sure you use the proper amount of rinse aid.

(See page 7.)

♦ Load items with concave bottoms tilted so as much

water as possible will run off.

♦ Unload the bottom basket first to avoid spilling water

onto the dishes when unloading the top basket.

♦ Certain plastics may need to be towel dried.

Plastic items

♦ Always check the manufacturer’s suggested care

instructions before washing plastic in your

dishwasher.

♦ Some high-acid foods can discolor plastic. You

should rinse these items if you do not plan to run the

dishwasher right away.

♦ Plastic items dry poorly and may need to be towel

dried.

Chipped or Broken Dishes

♦ When you load the dishes, be sure they’re securely

in place and will not fall over or strike against each

other during the wash.

♦ Load glasses between the tines, not straddling them.

♦ Move the baskets in and out slowly to avoid

slamming the dishes together.

♦ Make sure not to load dishes so high that the spray

arms could strike them.

♦ Make sure tall glasses and stemware will clear the

top of the tub when you push the basket in.

♦ Always load delicate items in the top basket.

♦ Do not overload the dishwasher.

♦ Do not jam the glasses together when loading.

Stains and discolorations

Stains or discoloration on dishes could be caused by a

number of things. Listed below are some of the most

common causes. See also “Washing Special Items”

on page 14.

♦ Too much iron or manganese in the water can cause

yellow or brown marks on your dishes. As a

temporary solution, in place of the prewash

detergent, use one teaspoon to one tablespoon of

citric acid crystals. If your model does not have a

If you should experience a problem with your dishwasher,

you should review the list of frequently encountered

situations on page 13. It could save you the cost and

inconvenience of a service call.

Even though the product is under warranty, if the problem

is not caused by defective product workmanship or

materials, you will be charged for a service call. Refer to

page 16 to determine what is and is not covered under

your warranty. If you’re still not sure, contact the ASKO

Advisory Center before you call a service technician.

To remove hard water spots, try the following:

1. Run dishes through a normal wash program.

2. Remove all metal dishware, such as cutlery, pans,

etc., from the dishwasher.

3. Do not add detergent.

4. Pour two cups of vinegar into a bowl and set the

bowl face up on the bottom rack of the dishwasher.

5. Run the dishes through a Normal wash program.

If this doesn’t work, try the same process with 1/4 cup of

citric acid crystals (available at most drug stores) instead

of vinegar.

softener container, you should consider installing a

water filtering system.

♦ If you have a model with a softener container, make

sure the container has salt and is set correctly (See

page 6.)

♦ Coffee and tea stains usually have to be removed by

handwashing in a solution of 1/2 cup bleach and

one quart of water. (Do not use on sterling silver or

silver plate.) Be sure to rinse these items thoroughly

before putting them in the dishwasher so there is no

bleach residue on the dishware.

Etching

If you have a cloudy film on your dishes that can’t be

removed, it could be etching. To prevent etching, try the

following:

♦ Use a good quality dishwasher detergent.

♦ Use less detergent. You may be using too much for

the water hardness in your area. (See page 5.)

♦ If you have a model with a softener container, make

sure the container has salt and is set correctly (See

page 6.)

♦ Do not overload the machine. Water should circulate

freely to ensure adequate rinsing and draining.

♦ Fill the rinse aid dispenser (unless you have soft

water in your area; in which case you may not need

a rinse aid.) (See page 7.)

♦ Use a lower water temperature setting.

♦ Do not use the Heat Dry option.

♦ Do not pre-rinse the dishes; just scrape off large

food particles and bones.

Page 13

Detergent left in compartment

♦ Be careful not to load items so close to the dispenser

that the cover will not open to release the detergent.

♦ The dispenser is not supposed to open when you

use the Rinse program.

♦ Your dishwasher detergent should be fresh and

stored tightly closed in a cool, dry place. Old or caked

detergent should be thrown away because it will not

dissolve properly and will leave a gritty residue on

the dishware.

♦ Wait until you are ready to start the dishwasher to

add the detergent.

♦ If you are using the Delay program, make sure the

dispenser is dry before adding the detergent.

♦ The detergent compartment only opens in the main

wash programs, not the Rinse program.

Dishwasher makes unusual noises

♦ This usually means that something is not loaded

properly. Make sure the dishes are securely in place

and that nothing has fallen between the basket tines.

Also, place small items in the small items

compartment and close the lid. (See page 4.)

Dishwasher leaks

♦ Use only unscented, granular automatic dishwasher

detergent. Using a liquid detergent could cause

oversudsing and leakage.

♦ You should always use fresh detergent.

♦ The amount of detergent needed for your dishes

depends on the hardness of the water in your area.

Contact your local utility company to learn the water

hardness in your area then refer to the chart on page

5 to determine the amount of detergent you should

use.

♦ Be careful not to overfill the rinse aid dispenser.

Spilled rinse aid could cause oversudsing and lead

to overflowing. Wipe away any spills with a damp

cloth.

♦ Make sure the dishwasher is level. (See the

installation instructions.)

Dishwasher runs too long

♦ If the temperature of the water entering your dishwasher

is below 120°, the dishwasher runs longer because it

heats the water to the proper temperature for the

program selected. Raising your water heater setting

may help to shorten the cycle times. If this doesn’t

resolve the problem, call the ASKO Advisory Center.

Dishwasher does not drain properly

♦ Make sure that the cycle was complete before you

opened the dishwasher. If not, allow it to complete

and check again.

♦ Some water left in the sump area near the drain is

normal.

♦ If the plumbing code in your area requires an air

gap, make sure that the air gap isn’t blocked or

plugged.

♦ If the unit is connected to a garbage disposer, make

sure the disposer is empty.

♦ If water backs up into the sink, check the garbage

disposer and trap for blockage.

♦ Check the dishwasher filters and drain area for

blockage. (See page 10.)

♦ Check for a kink in the drain hose.

Dishwasher does not fill properly

♦ Make sure the water supply is turned on.

♦ Make sure the dishwasher is turned on and the door

is closed securely.

♦ Check for crimps in the water feed line.

♦ The system is designed to detect an overflow. When

it does, it shuts off the inlet valve and circulation pump

and turns on the drain pump. (See “Overfill

Protection” on page 11.)

Dishwasher will not start

♦ Make sure the dishwasher is turned on and the door

is closed securely.

♦ Make sure the Delay option is not turned on.

♦ Check that the water supply is connected properly

and the water is turned on.

♦ Make sure the power cord is properly plugged into

the wall socket.

♦ Check your fuse box for a blown fuse or tripped circuit

breaker.

is dishwasher safe. If that isn’t possible, you might wash

one item of a set a few times and compare it to the rest

of the set to determine if washing it in the dishwasher

had any affect on it.
